Windows 10: App Identity CA Not Working

Upon startup, got a message that App Identity CA was not working. What is App Identity CA? Can it/should it be fixed? Thanks.

Mail app will not open on 10041.

Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.

The Microsoft Store, and the Xbox app doesn't work!

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to launch Microsoft Store, Xbox app and GameBar. I’ll certainly help you with this issue.



However, please let us know:

• Do you receive any error message?
  
• Are you aware of any changes made to the computer recently?
  
• Which build version of Windows 10 are you using currently? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  

Meanwhile, I would suggest you to refer the steps mentioned below:



For issues with launching Microsoft Store, I would suggest you to refer the steps mentioned in the article

Microsoft Store doesn't launch.



Method 1: Store app troubleshooter



I would suggest you to run the Store app troubleshooter and check. Refer the steps mentioned below:

1. Press Windows Logo key + I, to open Settings.
   
2. Click on Update & Security and select Troubleshoot from the left pane.
   
3. Scroll down, click on Windows Store apps and select Run the troubleshooter.
   
4. Follow the on-screen instructions.
   

Method 2: Re-register apps



If Store app troubleshooter doesn’t work, I would suggest you to try re-registering the apps using PowerShell. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select
   Windows PowerShell (Admin).
   
2. Paste the following command and press Enter:
   Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
   
3. Once the process is complete, restart the computer and check.
   

Method 3: New user account



If re-registering the apps didn’t work, try creating a new user account and check if the issue persists. Refer the article
Create
a local user or administrator account in Windows 10



Let us know the results.
